Be it known that l, (humus F. Mares, a ritirmn of the l'nited States, residin; at )liilnezilmlin. in the enmity of Hennepin and mm of Minnesota. have invented rertaln new and useful improvements in Typewrit lrrgphiarhinies. of which the following is sprrii ii ntimi.

" i. llntfllliflil relates to tvpewritlng ma l more particularly to a device to 'Lni with the on inary standard t p w The ohjert broadly is the provis 'w'i oi merhanisn'i by means of whirh enops or work sheets assoriated with the iiiiliiilllli m. or seuond machine it will om. matte-r he referred to. will have record vi thrrwn the same matter that is type in she usual manner on the ordinary tor. or first mat-hintas it will herein in i it Etfrlltil to. The nhjert more per- 1r v.hu'lr is to proiide for typewritingi on who. tin names and addresses of parties 1 n r. at iln some time are typewritten at iia head of rirrnlar letters. bills or ordinarv onrespondenue. These arts are performed s nnltaneo 'isly by the operator depressing the keys of the first machine in the ordinary manner. A further ohjeut is'thv provision of mwhanism which will aliow the varriagu oi the serond marhine to return to a selected position, proper for feeding in a new work pim'e when diseonneeted from the carriage of the first machine. A further ohjert is the oroiision oi meni'ianism whereby the rotatint. o' the platen of the second mz-xt'hine may he stopped in a selected position to bring the work piece. into the proper position for writing upon. A further ohjet't is the provision of mechanism by whi rh the iine spaw ing in either machine may he adjusted indepewh'ntlv of that in the other min-lime. A fnrther older-t is the provision of mevhanism \viwrelrv. at the will of the operator. the seeond marhine may he rigidly connevted to operate in unison with the 'rst. or disconnet-ted to allow the free operation of the Eirsi mavhine. further provision being made to temporarily disconnect the Carriages and iinespa .-ir1g mechanism of the'two machines so as to allow proper adjustment in relation EH ach other to begin writing properly.

'i'Lr till objerts and advantage of my in motion will appear in wnnertion with the detailed description thereof and are full pointed out in theclaims. v

The gear 166 meshes with an intermediate gear .168 and this gear in turn meshes i eh a gear 170 secured to the platen of the second ma chine. A- projection 172 on the iilil 152 as shown in Fig. 18 engages an mm 174 (roilnected to an arm 176 Whirh is lk owl at 178 and is engaged by a spring 1T7, while the connection between the arms 171 and 116 is by means of a hinge 180. 18? is: :1 spring tending to keep the arm 17-1 in the same plane as the arm 176, and 173 is a projection secured to the ma azine which engages and swings the arm 1 1. A projection 18% on the upper end of the arm 176 slides in a. slot 186 in an arm 188 fast to a sleeve 190 which has a key 192 engaged in a kevway in a collar 194 adjustable by means of a set-srrew 196 as shown in Fig. 18. Rigid on the coliar 194 is an arm 198 pivotallj' vomieoteii to a push rod 200 which constitutes a feeder for the envelope. On the rod 201; is a can: 202 adapted to engage a projection 2M on the top of the magazine. The point of the rod 200 is adaptedto engage under the flap 20? of the upper envelop ot' the stack of envelopes E205 as shown in Fig. 16. Springs 206 on the magazine engiige over the envelope and when the push rod 200 is lifted by the projection 204. an envelop is forced off these springs. hir immediately return into engagement with the underlying envelop and retain the same The push rod continues to advanve the envelop until it is forced hetwemi a roller 208 and the platen 87. The roller 208 is shorter than the shortest envelop intended to be used and is carried by spring-pressed arms pivoted to the franm of the carriage. The rollers 210 are the full length of the platen and are harried in :nrin )ressed arm 211 'iivoted to the mrriage. Rollers 212, one for each end of the envelop. are provided, and these rollers are mounted on arms 2141 on a square shaft 216. An arm 218 on this shaft. is engaged by a spring 220.

Fig. 2o shows the keymonnecting merhanism in its engaging position. while Fig. .32 shows it in its disengaged position.

The operation and advantages of my iniprnved machine will readily he understood from the foregoing desrription. lpou the operator depressing: any one of the keys of the ordinary keyboard. the ronnecting key hard of the first nuiel'iiul} will be operated to actuate the proper type-bar of tin first inn-- i'hine. and by means of the ronncrtions ljlt tween the key-bar and the (-orrespomliug type bar 114 of the secmid unu-hiue the (in velop therein will be impressed with the some character. \Vhen the key is released the upper lever 8 returns the type bar of the SOIUIltl machine in unison with the type bar of the first machine. Since ihe carriage 52 of the second rnnt-hiue is vonnerted by the llilIS T1 to the wart-h1g0 of the first machine, the c-arria'ges of the two machines will move step by step from right to left while a line is being; typewritten and will be returned again from left to right into position for writing another line.

In order to feed another envelop or work sheet into position tobc typewrittelrhy the serond machine, the operator (-lepresses the end 115 of the lever 111 and raises the rod 152 against the tension of the spring 1-18. This swings the arm 151- and lifts the end 161 of they pawl .158 of? the stop 16:2, allowing the pawl to engage the ratchet 159 and rotate the gear 164 secured to the shaft 156, \rliie-h in turn rotates the long gear 166 and through the intermediate gear 168 turns the gear 17o HQL'U red to the platen of the second inavhine in the proper (lirertion for feeding in vnvelops. As the rod 1525 is moved up the arm 17-1, resting'upon the projection 172, is moved and communicates motion to the :11'111 188 connez'ted to the sleeve 130 and oarryiu with it the collar 194 to which the arm 2H0 1s ronnected. thus giving a shifting motion to said arm which ei'igages under the in p 203 of the upper envelop in the mega zine. \Vhen the ram 202. en ages the projer-tion 204 the envelop is li ted above the retaining spring 206 and the spring then snaps hack and retains the underlying. en
